Abstract

A tire includes a carcass ply, a tread disposed radially outward of a crown region of the carcass ply, and a belt structure having an overall axial width substantially equal to a tread width interposed between the tread and the crown region in circumferential surrounding relation to the carcass ply. The belt structure includes a first belt layer and a second belt layer radially adjacent the first belt layer. The first belt layer includes a first reinforced composite with first reinforcement cords embedded in a first rubber matrix. The first reinforcement cords have a construction of 1100/4 dtex with a twist between 150 TPM and 250 TPM and a dipping tension between 100 mN/tex and 200 mN/tex.
